This seems like a simple problem, but I haven't found any sufficient answers through my two hours of scouring the internet! Needless to say, it's driving me a little crazy. It was working just fine less than 24 hours ago!

There is no sound whatsoever coming out of my speakers or headphones (each plugged in to the appropriate ports). Monkey is all updated; green checks everywhere. Output knob and phones knob are at maximum. Input/Output in Mac preferences is set for UX2. I've tried switching out usb cables and trying different ports. Tested headphones and speakers on other devices, they work. The only thing that changed was that I pulled out the usb cable and put it into a usb hub for a moment, then took it out and put it right back into the mac directly (I forgot, no hub with the UX2). Right after that, it stopped working correctly.

Also, when I try to use logic pro X and gearbox, it doesn't register any sound coming from the mic, and when I try to play back something I recorded just a few days ago using the exact same settings, I get this message:

Before line6 was called line6... they used to do r&d for other companies like alesis + others. and when those customers came to visit the offices of line6 (before it was called line6) and the receptionist needed to warn all the guys who were designing products for other companies (and for themselves... ) who were like 'in the back' the receptionist would announce over a tannoy 'tellephone call for 'fred smith' on line 6' the cunning part was that they only had 5 telephone lines, so it was the secret code for "hide your sh1t the feds are comin'" or "someone's coming, let's hide these PODs that we aren't going to release for another few years so they don't see them"

Tried uninstalling and reinstalling all drivers, resetting the mac, and installing pod farm 2. Still the same problem.

I also noticed when I set the audio preferences in my macs input/output to the ux2, it slows down youtube videos (still no audio), and when I switch it back to built-in, the videos resume their normal pace.

I am having the same problem with a PC. It was working fine last time I used it, now no sound. I haven't connected anything different. Cables checked. Drivers re-installed. Meters show input when I set it to input, however no output from monitors or headphones. Help?
